adjacent irregularly rugose; clypeus varying from yellowish to 
brown, with evident vertical rugosities, this and the labrum 
usually paler than adjacent parts. Antennae white at base, darker 
towards tip. Cervical shield and anal plate brown to black, with 
the usual three pale lines,—the lateral ones often becoming broad, 
pale patches. 
Parasites. 
The only evidences of parasitism of this species which came to 
our notice were presented by two lots of larvse, one obtained at 
the University June 12, among which, in the breeding cage, was 
presently seen a mass of parasitic cocoons, which yielded, June 19, 
a very small species of Meteorus seemingly undescribed. From a 
single cutworm of the other lot, which • had apparently shortened 
up for pupation, several examples of the same parasite emerged 
July 1, the larva being at this time dead upon the surface. 
The Greasy Cutworm. ^ 
(Agrotis ypsilon, Eott ) 
(Plate IV., fig. 2.) 
This species is mentioned here only to record the fact that in 
this latitude it was still actively at work in corn fields June 3 of 
last year. Most of the specimens were, however, full grown, and 
some shortening up for pupation, although others were scarcely 
more than half grown. An examination of our breeding cage 
showed puprn in the earth on the 17th June, and several imagos 
had emerged by the 24th. Most of the larvm of this rearing, how¬ 
ever, were parasitized by Tachina and Braconidae. 
The Variegated Cutworm. \ 
(Agrotis saucia, Huebn.) 
Although the relatively early development of this cutworm mak^s 
it probable that it is a two-brooded species, I do not know that 
examples of a second generation have been taken in any stage. 
According to Biley’s notes, made at St. Louis, it seems to hiber¬ 
nate most commonly as pupa or imago, its eggs having been re¬ 
peatedly taken in April; but the occurrence of a full grown cut¬ 
worm of this species in the grass near my office in January, 1888, 
shows that it sometimes passes the winter m the larval stage. i 
The caterpillars of the spring brood may feed in this latitude 
until the first of June, sometimes pupating, however, by the mid¬ 
dle of May, and sometimes not entering the earth until the mid¬ 
dle of the following month. The imagos in our breeding cages 
began to emerge June 14, 1888, but the moth did not become 
.
